What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
How is genotype determined in individuals?
Genotype is determined by the combination of genes inherited from an individual's parents. Each gene has different variations called alleles, and the specific combination of alleles a person has for a particular gene determines their genotype. This combination is determined during the process of genetic inheritance, where one allele is inherited from each parent.
What is an example of allele?
an allele is an alternative form of a gene that governs a characteristic, like hair or eye color. an individual gets 1 allele for each charecteristic from each parent. There are dominant alleles and recessive alleles. The dominant allele is the allele that is the person's physical appearance, and the recessive allele is the one that isn't visible but the person has in his/her genotype.
A person with a heterozygous gene?
A person with a heterozygous gene has one dominant allele, usually represented by a capital letter, and a recessive allele, which is usually represented with a lowercase letter. So an example of a heterozygous gene would be Rr
Which of the following is a genotype TA ta Tt or none of these?
Tt is a genotype. Each letter is called an allele and represents a different trait. For instance, the T could stand for tall, and the t could stand for short. Because the T is a capital letter, it is the dominant trait. In the case of Tt, the person would be tall. If the genotype was TT, the person would again be tall. If the genotype was tt, the person would be short. All traits are represented by two or more alleles. Things like blood type are represented by multiple alleles.
What alleles are received during fertilization?
During fertilization, an individual receives one allele for each gene from each parent. This means that a person inherits one allele for each gene from their mother and one allele from their father. The combination of alleles received determines the individual's genotype for that particular gene.

What are the two ways to have blood type A bio?
A person can have type A blood with a homogenous genotype (two A alleles). In addition, you can be heterozygous A (one O and one A allele).
What is an example of a heterozygous genotype?
Genotype means the particular alleles an individual has alleles are just a kind of gene and a gene is a section of DNA which codes for a particular protein or characteristic in an organism. Heterozygous is when a person has 2 alleles for the same characteristic like hair you could have the allele for both blonde or brown hair but due to the blonde one being recessive (ie not as powerfull/strong), you would not know. So, an example would be WBWb: B = Brown b = blonde W= allele so for hair a heterozygous person would have the genotype WBWb.
What is the allele combination of an individual?
An allele combination refers to the specific alleles that an individual has for a particular gene. For example, a person may have two alleles for eye color, one from each parent, which could be a combination like "brown-blue" or "brown-brown". Allele combinations determine an individual's unique genetic makeup for a given trait or gene.
How do you find the possible genotypes of the children of a woman with blood type O and a man with blood type AB?
There are three alleles for blood type which can be represented by IA, IB, and i. A person with blood type O has the genotype ii. A person with blood type AB has genotype IAIB. If these two people produce children, those children will inherit one allele from each parent. They will therefore certainly inherit the i allele from their mother and either the IA or the IB from their father. The children with the genotype IAi will have type A blood, since the IA allele is dominant to the i allele. The children with the genotype IBi will have type B blood, since the IB allele is also dominant to the i allele.

What is the genotype of a pure-breeding myopic person?
A pure-breeding myopic person, who consistently passes on the myopic trait to their offspring, would typically have a genotype that is homozygous for the myopia allele. This means they would have two copies of the allele associated with myopia, often represented as "mm" if "M" represents the normal vision allele and "m" represents the myopia allele. Thus, their genotype would be "mm."
How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
